Definitions

  • the Langmuir-Blodgett (LB) process is predominantly used to produce ordered layers of organic polymers with long-chain side groups.
  • molecules are spread on a water surface and the long alkyl side groups are arranged in parallel by reducing the area per molecule.
  • the molecules are pulled up and down on a substrate.
  • One monomolecular layer is transferred per dive while maintaining its order.
  • Amphiphilic molecules are used for the construction of LB films, i.e. Molecules that have a hydrophilic end (a "head") and a hydrophobic end (a "tail”).
  • a hydrophilic end a "head”
  • a hydrophobic end a "tail”
  • polymeric LB films have also already been produced.
  • Regular LB layers of homopolymers can generally only be built up if the alkyl side chain and the polymer main chain are separated by a hydrophilic, flexible segment, the “hydrophilic spacer”.
  • the "hydrophilic spacers" do not completely decouple them.
  • DE-A 3843194 has already proposed films made from polymers which can be prepared from mixed-chain, amphiphilic monomers which are accessible in several synthesis stages.
  • the present invention solves this problem. It is based on the synthesis of single-chain amphiphilic monomers, their non-polar residue is introduced in a simple manner with long-chain alcohols or amines.
  • the single-chain amphiphiles make it possible to use relatively short, hydrophilic spacers that are easier to synthesize in order to decouple the order tendencies of the polymer main chain (tendency to polymer tangle) and alkyl side chain (tendency to crystallization) in the homopolymers.
  • the monomers of the general formula (I) can firstly be reacted with a dicarboxylic acid of the general formula (III) HOOC - X - COOH (III) or an activated derivative of this dicarboxylic acid, such as an acid anhydride, acid ester or acid halide, with an unsaturated alcohol of the general formula (IV) to produce the monoester and subsequent condensation with a long-chain alcohol or primary amine of the general formula R2H.
  • a dicarboxylic acid of the general formula (III) HOOC - X - COOH (III) or an activated derivative of this dicarboxylic acid, such as an acid anhydride, acid ester or acid halide
  • an unsaturated alcohol of the general formula (IV) to produce the monoester and subsequent condensation with a long-chain alcohol or primary amine of the general formula R2H.
  • the monomers of the general formula (II) are obtained by reacting a carboxylic acid (V) or a reactive carboxylic acid derivative of this carboxylic acid with an alcohol or primary amine of the general formula (VI), preferably synthesized in the presence of a tertiary amine.
  • carboxylic acid chloride or carboxylic anhydride can be used as reactive carboxylic acid derivatives.
  • these monomers are homopolymerized or else with others Copolymerized monomers.
  • Several other monomers can also be copolymerized.
  • the comonomers can also be unsaturated monomers with long alkyl chains which have at least 8 carbon atoms, for example compounds of the general formula VII where p is an integer from 7 to 21, or other monomers of the formula (I) or (II) or monomers as described in the above-mentioned publications and DE-A 38 431 904. Reference is therefore expressly made to these references.
  • vinyl monomers which contain a hydrophilic group and are preferably water-soluble, such as e.g. Itaconic acid, fumaric acid, maleic acid, acrylic, cyanoacrylic and methacrylic acid or derivatives thereof can be used.
  • the copolymers according to the invention are prepared starting from at least 10% by weight, preferably at least 20% by weight, of a monomer of the general formula (I) or (II).
  • the polymerization is preferably carried out by free radicals, in particular with the addition of a free radical generator.
  • azo-bis-isobutyronitrile or peroxides are used as radical formers.
  • polymers with a low molecular weight can be obtained.
  • the polymers according to the invention have a good suitability for producing a layer element even from a molecular weight of approximately 5000 daltons.
  • the average area per repeating unit is calculated from the dimension of the surface, the spreading volume and the concentration of the solution. Phase transitions in the compression of the molecules can be followed in the shear surface isotherm.
  • the molecules are pushed together with a barrier, the alkyl chains being oriented essentially perpendicular to the boundary layer as the surface density increases.
  • the film is removed from the water surface with constant thrust by immersing or immersing a suitable carrier while maintaining order.
  • Water or aqueous solutions are usually used as the subphase for monofilm production. But there are also other liquids with high surface tension, such as. B. Glycerin, glycol, dimethyl sulfoxide, dimethylformamide or acetonitrile can be used.
  • any solid, preferably dimensionally stable substrates made of different materials can be considered as supports.
  • the substrates serving as a layer support can, for example, be transparent or translucent, electrically conductive or insulating.
  • the substrate can be hydrophobic or hydrophilic.
  • the surface of a per se hydrophilic substrate on which the LB layer is applied, can be hydrophobic.
  • the surface of the substrate to be coated should be as clean as possible so that the formation of a thin, orderly layer is not disturbed. In particular, the presence of surface-active substances on the surface of the substrates to be coated can impair the layer production. It is possible to provide the substrates serving as a layer support with an intermediate layer on the surface to be coated before the LB films are applied, in order, for example, to improve the adhesion of the film to the substrate.
  • metals such as gold, platinum, nickel, palladium, aluminum, chromium, niobium, tantalum, titanium, steel and the like can be used as materials for the substrates.
  • plastics such as, for example, polyester, for example polyethylene terephthalate or polybutylene terephthalate, polyvinyl chloride, polyvinylidene chloride, polytetrafluoroethylene, polystyrene, polyethylene or polypropylene.
  • Semiconductors such as silicon, germanium or gallium arsenide or glass, silicon dioxide, ceramic materials or cellulose products are equally suitable for the substrates.
  • the surface of glass and other hydrophilic substrates can be made hydrophobic in a manner known per se by reaction with alkylsilanes or hexamethyldisilazane.
  • the choice of substrate materials depends primarily on the intended use of the layer elements produced from the film according to the invention. As a rule, transparent, translucent substrates are used as layer supports for optical elements. If the layer elements according to the invention are used, for example, in electronics or in electrochemical processes, they serve as substrates in particular electrically conductive materials, such as metals or indium tin oxide or metallic surface layers, for example on plastic films or glass.
  • the substrates serving as supports for the films according to the invention can have any shape, depending on the intended use.
  • they can be in the form of films, foils, plates, tapes or cylinders, or they can be selected from any other shape.
  • the substrates will be flat, flat substrates, e.g. Films, foils, plates, tapes and the like.
  • the surface of the substrates to be coated is preferably smooth, as is customary for the production of LB films.
  • the films according to the invention can be applied to one or both surfaces of the substrate.
  • the polymers according to the invention are notable for good producibility of a multilayer structure with few defects, the layer structure having good temperature stability.
  • Such films on substrates are suitable, for example, for optical waveguide systems or for the production of filters for optical purposes. Due to the low critical surface tension, the films are also suitable for improving the friction properties of materials, for producing protective layers and for other relevant applications.

  • the solution is placed in a three-necked flask with a reflux condenser (with gas discharge tube and bubble counter), thermometer and gas inlet tube and flushed with nitrogen for one hour at room temperature.
